ILQPRQYEMNT. IN CULTIVATAORS.

The Schedule-referred to in these Letters Patent and `making pax-tof tho'ame.

To-all whom 'it may concern;

Be it known that I, F. L@ PERRY, of Canandaigua, in the county of Ontario, and State of New York,

have invented va new and useful Improvement in Oui? tivators; and I do hereby'de'clare Vthat the following and vexact description thereof, which will enable those skilled in the art to malre and use the same, reference being had to the accompanying drawings, frming-a part oi' this specication.

This invention relates to a new and improved cultivator, of that classwhich are construeted-with-a'view of being expanded and contracted to suit the width of the spaces between the rows of plants.

- The object of the invention is to obtaina enltivator of' this class which will, in being expanded orcon tract-ed in width, automatically adjust the teeth, so

that the latter will at all times, or under any adjustbe in line with the draught, or i ment of the barrow, all the teeth of the cultivator be-in paxallelplanes.

The invention has further for its objecta means for regulatingl the depth of the penetration of-the teeth into the earth.. Y

In the accompanying sheet of drawings--l Figure 1 is a side sectional View of my invention,

taken in the line :c z, fig. 2. Figure 2,.an inverted plan ofthe same.

The ameof my improved cultivator is composed ing forwaidof the other two A A, and-having a clevis, B, attached to it by a pivot-bolt, a, in the lower part of which a gauge-wheel, O, is iitted..

The i'ont ends of the beams A A are secured by 'pivot-boltsb-b, hetweenthe ends of platesD D, which 4are firmly bolted at rightangles to' the central beam A.l

This admits of the expanding and contracting of the 4beams A A, as rnay be required.

' Ev E represent the teethothe' eultivator, two teetlr E beingattached to 'each beam -A,'and one tooth E' being attached to the central beam A'. Y

The tooth-Eis permanently'secrired .to itslbeam A but th'eteeth E are pivoted, to their beams A A, the upper partsV of said teeth beingforked, as' shown in Iig. 1, and the front prongs c passing through thev front ends of plates, or Washers d, at the under sides ofsaid beams. and also through the beams, and' secured by nuts e, on their upper ends.

The rear prongs f of the teethsimply pass through the plates d, in order to form a connection therewith.

Each 'plate 4thas an ,arm, g','projecting 4from it at right angles, 'and 'the -oute'r'ends of these armsare A A A',-the central beam A extendprovided with -lips.h., the lips ot' vone arm being bent o r lapped around the edges of its fellow arm, at the opposite side of the machine. derstood by referring to fig. 3. The arms g i the two rear teeth-E of 'the beams A. A pass-through a guide, j, which is fitted in anoblong' slot, i, in the rear partofthe central beam A', (said guide having a nut,j,) by screwing up, while the guide is made-to serve as aclamp-to secure the beams A Ain position,l at a' greater or less distance apart, as desired.

of the cultivator are turned each l'time the beams 'A A are adjusted, and said teethalways kept in line with the draught, -t-he plates ll serving` as levers to turn or adjust the teethv as the beams A A are moved. The elevis Bis. composedof two-parts or plates la k, one at each side of the-front part of beam A', and the rear portions of these plates are of segment-form, and perforated withhole's 1, shown'l clearly in fig. 1.

A rod, or 'bolt, m, is passed through any of these holes, underneath the beam A', in order to elevate or furrow required,land the under bolt'm is held up ina' lease the -bolt m, when required, by means of a slide or cord, o`.. Y

Having thus described my' invention,-

f1. The attaching ofthe teeth E to the beams A,'by having the front prongs c. of the teeth pass through the front ends of plates d, and the rear prongs fitted in the vrear parts of the plates, 'in combination with the arms g of the plates, `the arms of eachfjpair of arranged substantially as shown and' described, to admit'ot the turning or, adjusting of the teeth` as' the beamsA A are expandedor contracted, as s et forth.

of the-bolt m, fitted in any of a series of holes, `l, in said plates, in connection withthe spring-catch G, all

o`f the 'gauge-wheel C, substantially as and for the pur'- pose setforth.
